Overview
The BD6583MUV-AE2 is a white LED driver IC designed for medium to large LCD panels. It integrates a PWM step-up DC/DC converter and a current driver. The device supports a boost topology with an input voltage range of 2.7 V to 22 V. It provides six output channels, each capable of driving up to 25 mA, allowing for a maximum total output current of 150 mA. The converter can boost voltage up to 42.5 V, supporting configurations of up to 72 LEDs (12 in series, 6 parallel strings). The switching frequency is 1 MHz. It operates within a temperature range of -30 °C to +85 °C.
Feature Summary
- Integrates high-efficiency PWM step-up DC/DC converter with maximum efficiency of 93%.
- Features six high-accuracy current drivers with good matching characteristics.
- Supports wide-range, high-precision brightness control via external PWM signals.
- Includes protection functions such as over-voltage protection, thermal shutdown, and over-current limit.
Applications
- White backlighting for medium-sized LCD panels
- White backlighting for large-sized LCD panels
- LED lighting systems requiring high accuracy and low luminance unevenness
Procurement Notes
Verify the specific suffix AE2 against the manufacturer's latest documentation to confirm compliance and revision status. Check the lifecycle status, as related models in this series may be marked as not recommended for new designs. Ensure the ordering information matches the exact package type and tape quantity specified in the official datasheet before finalizing procurement.
Selection Notes
Select this component for applications requiring precise current matching across multiple LED strings to minimize luminance unevenness. The wide input voltage range suits battery-powered or variable supply systems. Consider the 1 MHz switching frequency for passive component size optimization. Verify that the required number of LEDs does not exceed the 72 LED capacity supported by the six-channel architecture.
Part Context
The BD6583MUV-AE2 belongs to the BD6583MUV series of LED lighting drivers manufactured by ROHM Semiconductor. It is classified as a switching regulator type driver specifically optimized for white backlights. The device combines power conversion and current regulation in a single integrated circuit to simplify design for LCD panel illumination.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Consult the manufacturer for direct replacements if this component is obsolete or unavailable.
